FRED L. KUTCHENREITER, F SPRINGDALE, PENNSYLVANIA.

INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented July 1, 1919.

Application filed September 1, 1918. Serial No. 252,596.

To all whom it may concern Be it known that I, FRED l1. KUTGHEN- REITER, a citizen of the United States, residing at Springdale, in the county ofAllegheny and State of Pennsylvania, have in vented a new and useful InternaLCombustion Engine, of which the following is a specification.

It is the object of this invention to provide an internal combustion engine having novel means whereby the intake stroke will be shorter than the stroke delivering the power derived from combustion, thereby doing away with a waste or loss of pressure, at the end of a stroke, the variable stroke giving an increased amount of power with a reduction in fuel.

Within the scope of what is claimed, a mechanic may make changes without departing from the spirit of the invention.

In the drawings :-Figure 1 shows in section, a portion of an internal combustion engine wherein the invention has been embodied; Fig. 2 is a section through the piston at right angles to the cutting plane in Fig. 1; Fig. 3 is a diagrammatic. detail showing a modification.

The numeral 1 denotes the cylinder of an internal combustion engine in which operates a piston 50 provided with oppositely disposed side supports 2, sustained by webs 3. Hangers 4 are provided and fit .within the piston 50*. The upper endsof the hangers have their inner faces in contact as shown at 7 and lie between the supports. The lower ends of the hangers 4 are spaced as shown at 8. The hangers are united by securing elements 6 and are held in the piston 50 by means of a retainer or rod mounted in the side supports 2. A shaft 10 is journaled in the lower ends of the hangers 4 and has a crank 11 operating in the space 8 between the lower ends of the hangers 4.

The upper end of a pitman 14 is carried by the crank 11, the lower end of the pitman being assembled with a crank 15 on the main shaft 16 of the engine.

It is not necessary that the crank 11 be employed. Any mechanical equivalent thereof may be used: or, if desired, the shaft 10 (Fig. 3) may carry an eccentric surrounded by a strap 14 on a pitman 14.

It will be understood that when the pitman 14: and the piston move together. they will have, also, a slight, relative movement, because the pitman is connected with the crank 11 of the shaft 10, a variable clearance resulting, carrying with it the advantages mentioned in the opening portion of this specification.

. ll claim The combination with the piston and the crank shaft of an internal combustion engine, of hangers in the piston the outer ends of the}, hangers being spaced; a retainer engaging the piston and the inner ends of the hangers; and a pitman connected with the crankshaft; a second shaft journaled in the outer ends of the hangers and including means operating in the space between the outer ends of the hangers for connecting the second shaft eccentrically with the itman.

In testimony that 1 claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
